該基因編碼的蛋白質是一種堿性亮氨酸拉鏈（bZIP）轉錄因子，在血緣特異性造血調控中起重要作用編碼的核蛋白抑制ets1介導的髓系細胞中紅系特異基因的轉錄。這個基因不含內含子[由RefSeq提供，2008年7月]
The protein encoded by this gene is a basic leucine zipper (bZIP) transcription factor that plays an important role in the regulation of lineage-specific hematopoiesis. The encoded nuclear protein represses ETS1-mediated transcription of erythroid-specific genes in myeloid cells. This gene contains no introns. [provided by RefSeq, Jul 2008]
